General Safety Instructions
Loudspeakers produce a static magnetic eld even if they are not connected or are not in use. Therefore make
sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which
may be impaired or damaged by an external magnetic eld. Persons with cardiac pacemakers must maintain a
safe distance.
The minimum recommended safety clearance is 1 m.
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems
are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels
(from approx. 90 dB SPL) can cause hearing damage if people are exposed to it over a long period.
All connected cables must be laid in such a way that they cannot be crushed by objects and that nobody can
step on them! Replace damaged cables immediately and do not use them!
Use only accessory parts specied by Voice-Acoustic or original accessory parts from Voice-Acoustic. Check all
cabinets and accessories regularly for wear and replace them if necessary.
Do not set up the loudspeakers in places where they are permanently exposed to moisture, dust, dirt or direct
sunlight.
Care
Wipe the surface of loudspeakers only with a damp cloth and pure water. In case of heavy pollution, repeat the
above procedure several times if necessary. Do not use any chemical additives or aggressive detergents, as
these may harm and damage the surfaces.
Transport and storage
When transporting and storing the unit, it is important to ensure that the surface and front grill of the loudspe-
aker are not damaged. Moisture can penetrate through exposed wood surfaces and cause the wood to swell.
A bent or broken front grill will no longer adequately protect the sensitive speaker membranes. In addition,
appreciable dust deposits may considerably impair the functionality of a loudspeaker membrane. For this rea-
son, the loudspeakers should be transported and stored in a safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from Voice-Acoustic:
■Carrying bag for up to 4 x Alea-4 with u-bracket (Art.-Nr. 500042000)
■Heavy duty ightcase for up to 4 x Alea-4 (Art.-Nr. 505003000)
Note: The original packaging is unsuitable as permanent storage and transport packaging!
Warranty
The warranty period is 24 months from date of delivery.
On our choice we will eliminate any lack of conformity with repair or with replacement of the faulty goods. The
place of performance for warranty services is Voice-Acoustic headquarters in Dörverden. In case of remedy of
defects, the buyer shall bear all costs resulting from transportation of the goods to Voice-Acoustic headquarters
in Dörverden.
The ordering party is not entitled to remedy the defect by itself or to organise a replacement and to charge
such activities to Voice-Acoustic. In case of self remedy by the ordering party the warranty given by Voice-
Acoustic becomes void.
Warranty doesn’t apply to parts of wear and tear, such as threaded points, Phoenix Contact connectors and the
SpeakON®connectors.

Connections
The speaker has two loop-through Neutrik NL4 SpeakON®IN/OUT connectors. They use the 1+/1- connection
pins. Additional loudspeakers can be looped through via the second connector. 1 x Phoenix Contact connections,
4-pin divided into 2 x IN/OUT, through-wired with SpeakON®.

Setup
The Alea-4 loudspeaker is designed for standing, vertical and horizontal operation. A variety of accessories is
available from Voice-Acoustic to securely attach the loudspeaker safely on tripods, distance rods or hanging
it from on trusses, ceilings and walls. Ensure that the loudspeakers are securely attached to prevent personal
injury and damage of property.
Connecting cables
When connecting the cables to the loudspeaker, ensure that the polarity (+/-) and pin assignment (1/2) is
correct. Incorrect connection results in a signicant change in the loudspeaker sound characteristics and may
damage the compression driver.
The two connection sockets on the back of the loudspeaker can be used to link multiple loudspeakers on a
single amplier. Note that parallel connection reduces the total impedance (Ω) seen by the amplier. The total
impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the
amplier.
Voice-Acoustic recommends to use the available 4 x 4 mm² Speakon cables for mobile use.
We recommend wiring the basses with at least 4 mm² in installations. The cables of the tops in installations
must be suciently dimensioned according to impedance, power and cable length.

Operation
The Alea-4 is exclusively intended for operation with Voice-Acoustic system electronics with internal DSP cont-
roller: the HDSP power ampliers or powered by the free 800 W amplier channels of the self-powered subwoo-
fers.
Make sure the appropriate preset has been selected before connecting the speaker to the system power amp or
self-powered subwoofer.
Using the wrong preset can damage parts of the loudspeaker.
Note: If the Modular-10 is not operated on the intended Voice-Acoustic system electronics, the manufactu-
rer‘s warranty for the loudspeaker expires!

Mounting the U-bracket
1. Remove the M10 countersunk screws (A) on both sides of the
loudspeaker.
2. Use the supplied M10 knurled screws (B) including plastic was-
hers to mount the U-bracket.
3. To protect the coatings, place the plastic washers between the
knurled screw, U-bracket and loudspeaker.
Mounting wall holder for hidden mounting
To be able to install the loudspeaker at on the wall, you must use
the 4-pin Phoenix Contact connector in the recessed connection
panel.
1. Mount the wall bracket at the desired location using the appro-
priate xing material. The two M4 x 20 mm grub screws (C)
point upwards!
2.
Note: The loudspeaker cables must be led out of the wall in the
area of the recessed connection eld!
Connect the loudspeaker via the Phoenix Contact.
3. Hang the loudspeaker into the two grub screws.
4. Turn the bottom set screw out through the small opening at the
bottom (D) until it is ush with the edge of the housing.
Installation with the U-bracket
The U-bracket can be used to install the speaker on walls (E), cei-
lings (F), oors (G) and tripods.
